Phthalates – they’re all around us and could be having some strange effects…

“Phthalates are a group of ubiquitous chemicals present in many consumer products, including building materials, furnishings, clothing, paints, food packaging, toys, personal care products and pharmaceuticals. Many of them are or have been produced in very large quantities. Phthalates can be released into the environment by leaching, evaporation, migration, abrasion or application of phthalate-containing personal care products. Due to their widespread use, the general population is continuously exposed to phthalates.”

The research paper that is the source of this quote is looking at children’s exposure to phthalates, by measuring breakdown products in their urine. It also looks at how the phthalates are getting into the children, and concludes that for some of the phthalates much of it is coming from dust and indoor air, whereas for others they are coming from other sources. This study also finds that many of the children in the study are being exposed to above the safety level of some of the phthalates.

It’s worth noting that the use of some – but not all – phthalates is controlled in the EU – but these controls are not always obeyed, as in the case of the Loom Band Charms.

Phthalates are associated with a whole range of toxic affects, including hormone disruption, as summarised in the paper:

“phthalates are known to be developmental and reproductive toxicants. Indications exist that they may impact genital development, semen quality, children’s neurodevelopment, thyroid function, onset of puberty in females and that they may possibly cause respiratory problems”

There’s new research coming out about the potential impacts of phthalates all the time – here are two recent examples:

Impact on baby boys

Exposure to the phthalate DEHP is known to lead to a reduction in the distance between the anus and genitals in baby boys; new research has found another phthalate, DINP, seems to have the same effect in Swedish boys. DINP is increasingly being used in soft PVC flooring materials for example, replacing DEHP. The authors query this:

“These findings call into question the safety of substituting DiNP for DEHP in soft PVC, particularly since a shorter male AGD has been shown to relate to male genital birth defects in children and impaired reproductive function in adult males and the fact that human levels of DiNP are increasing globally”

Impact on Libido?

The latest research that caught the attention of the UK media was on phthalates & libido:

Elizabeth Salter Green, director of the campaign group CHEM Trust, said: “Male and female sexual health is exquisitely sensitive to sex hormones and DEHP is a major hormone disruptor and feminises the male.

“Our exposure to DEHP is constant as it is used in so many consumer products made of soft plastic like PVC flooring and shower curtains. However, the phthalate leaches out of the product and we become exposed. It is time for industry and regulators to move away from major gender benders such as DEHP and replace hormone disruptors with safer alternatives.”

Rebecca Sokol, the ASRM [American Society for Reproductive Medicine] president, said: “Exposure to endocrine- disrupting chemicals is difficult to avoid in our society. As we learn more about the effects they have on human health and reproduction, we are realising that we need to find ways to protect ourselves from them and find alternatives to their use.”

A Chemical Industries Association spokesman said: “We are not aware of any globally accepted tests which can yet measure the effect chemical exposure may have on libido, but this is an interesting field of work.”

CHEM Trust’s work requires an in-depth and accurate analysis of the science and policy of chemicals, and the communication of this analysis to policymakers and other stakeholders.We now want to increase our capacity in this area, so we are recruiting a new Scientist to the team.Please share this job with anyone who you think might be interested!www.chemtrust.org/chemicals-policy-expert/...
